Cytophotometric and cytogenetic characteristics of primary hepatomas induced in Wistar rats by aflatoxin B1.
Karyograms of the primary hepatomas induced in Wistar rats by aflatoxin b1 exhibited hypodiploid chromosome sets, and destruction of the chromosomes. Cytophotometric investigations showed a decrease of DNA content in the neoplastic cells, even to about 40% of DNA content in the normal hepatocytes in rats. In the neoplastic destruction of the chromatin material in these hepatomas breaks and deletion of the chromatids predominate.
